Missing stderr for failed test XML creation

[Flamefire]

Description of the problem / feature request:

I'm running some test of TensorFlow using bazel but on our multi-core POWER9 system it fails with e.g.

ERROR: /dev/shm/s3248973-EasyBuild/TensorFlow/2.4.0/fosscuda-2019b-Python-3.7.4/TensorFlow/tensorflow-r2.4/tensorflow/core/platform/BUILD:1142:11: failed (Exit 1): generate-xml.sh failed: error executing command

I.e. there is no good error message, it simply failed to execute that script which comes from the Bazel installation. I verified that the executed command (bazel -s) runs correctly and the script hence also exists

The problem is an unset LD_LIBRARY_PATH, see #12579, but the bug here is that stderr is not reported which made the trouble-shooting process incredibly laborious.

Bugs: what's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

Sorry, only thing I have is the command I use to test TF:

bazel --output_base=/dev/shm/s3248973-EasyBuild/TensorFlow/2.4.0/fosscuda-2019b-Python-3.7.4/tmptspeEg-bazel-tf/output_base --install_base=/dev/shm/s3248973-EasyBuild/TensorFlow/2.4.0/fosscuda-2019b-Python-3.7.4/tmptspeEg-bazel-tf/output_base/inst_base --output_user_root=/dev/shm/s3248973-EasyBuild/TensorFlow/2.4.0/fosscuda-2019b-Python-3.7.4/tmptspeEg-bazel-tf/output_user_root --host_jvm_args=-Xms512m --host_jvm_args=-Xmx4096m test --compilation_mode=opt --config=opt --subcommands --verbose_failures --config=noaws --jobs=64 --copt="-fPIC"  --distinct_host_configuration=false --test_output=errors --local_test_jobs=1 --build_tests_only --test_tag_filters='-no_gpu,-no_oss,-oss_serial,-benchmark-test,-no_oss_py37,-v1only' --build_tag_filters='-no_gpu,-no_oss,-oss_serial,-benchmark-test,-no_oss_py37,-v1only'  --//tensorflow/c:c_test

What operating system are you running Bazel on?

RHEL 7.6

What's the output of bazel info release?

release 3.4.1- (@non-git)

If bazel info release returns "development version" or "(@non-git)", tell us how you built Bazel.

EXTRA_BAZEL_ARGS="--jobs=176 --host_javabase=@local_jdk//:jdk" ./compile.sh

Have you found anything relevant by searching the web?

#12579 #4137

Any other information, logs, or outputs that you want to share?

No updates here? I guess this still happens

encountered the issue generate-xml.sh failed: error executing command, but it is difficult to reproduce.
